Название: Third Generation CDMA Systems for Enhanced Data Services

Авторы: Mandyam G.D., Lai J., Gibson J.D.


Until now, most wireless devices have been used for voice transmission, but the new third generation of wireless devices promise greatly enhanced delivery of both voice and data communications. These devices are currently under development and are being built using the two major CDMA (code division multiple access) systems, cdma2000 and wideband CDMA. These telecommunication systems use signal codes to receive voice and data information. This authoritative new book reviews both of these systems and deals with the challenges engineers face in bringing these next generation devices to market.

The authors work at Nokia, one of the world's leading companies involved with the design, development, and manufacture of wireless telephones and devices. They are closely involved within Nokia and the industry in working with CDMA standardization to bring this technology to the consumer. This is the first book to cover both of the leading CDMA standards (cdma2000 and wideband CDMA), and it provides an authoritative, current review of the newest third generation technologies.
This book is ideal for the engineers developing wireless devices (at Nokia, Ericsson, Qualcomm, Motorola, etc.), as well as for those in the service sectors (i.e. AT&T, Verizon, Voicestream, Quest, etc.).

The use of mobile communication devices has grown phenomenally throughout the world during the last few years. With strong consumer demand to increase data delivery (large emails, browsing the Internet on wireless devices, transferring video images, etc.), engineers are faced with the challenge of enhancing CDMA to provide larger data capabilities while improving voice signals for clearer reception.

In November2001 the U.S. Federal Communications Commission released a much broader band of frequencies to wireless service providers, which will speed up the development of these systems.
